Abstract (en)
[origin: EP1967834A2] The spark plug has a longitudinal borehole (3) formed in a housing (2) for holding an insulator. The housing has a borehole (10) for holding a pressure measuring device. Another borehole (21) is provided in the housing for accommodating a fiber-optic light guide that opens out into a combustion chamber. An axis (21') of the borehole (21) runs inclined to an axis (10') of the borehole (10), where the longitudinal borehole is arranged parallel to a spark plug axis, and the axis of the borehole is provided at a distance from the spark plug axis (1').
